§ Mr. Aubrey Jones
Beyond the statement that my Department is working on research into methods, including infra-red methods, of detecting ballistic missiles at long range, I regret that, on security grounds, there is nothing I can say.
§ Mr. Jones
The hon. Member, and all hon. Members, have a right to know a great many things, but, on the other hand, one has to balance that against the desirability of not allowing the enemy to know certain things. [HON. MEMBERS: "What enemy?"] A potential enemy, any enemy. For instance, if I were to give the hon. Member a full answer to this Question, I should be informing an enemy how to develop ballistic missiles so as to defeat any future defence measure.
§ Mr. G. Brown
Since the right hon. Gentleman has joined other Ministers in great secrecy in the House, had we not better ask Mr. Chapman Pincher if he can get the information from his sources and publish it in the Express?
§ Mr. Emrys Hughes
Is the right hon. Gentleman aware that the House has been told that the cost of the V-bomber is about £700,000? If we have been told the cost of the bomber, why cannot we be told the cost of these ballistic missiles?
